We can just imagine LG G Flex owners repeating the action that shows off how the phone does actually live up to its name. As repeated in the video below, placing the phone screen-side down and placing some pressure on the middle of the back cover will result in the phone flexing.
One of the cool features of the LG G Flex is the self-healing back cover that helps hairline scratches disappear on the rear of the phone. This process has to be seen to be believed, which is why you can see it work for yourself on the second video below.
Thanks, Anonymous Tipster!
